Here's a breakdown:

* Incident Ray: The ray of light that hits the mirror.

* Reflected Ray: The ray of light that bounces off the mirror.

* Normal: An imaginary line perpendicular to the mirror's surface at the point where the incident ray strikes.

* Angle of Incidence: The angle between the incident ray and the normal.

* Angle of Reflection: The angle between the reflected ray and the normal.

The Law of Reflection states that the angle of incidence is equal to the angle of reflection.
